SLED-BRAKE.

SPECIFICATION forming part of Letters Patent No. 277,775, dated May 15,1883. Application filed March 17, 1883. (No model.)

To all whom it may concern Be it known that I, NEWTON PARKER, a citizenof the United States, residing at Pulaski, in the county ofOswego andState of NewYork, have invented certain new and useful Improvements inSled-Brakes; and I do declare the following to he a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing bad to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

Figurel of the drawings is a vertical sectional view of my brake. Fig. 2is a top view, and Fig. 3 is-a cross-sectional View of the same.

This invention has relation to sled-brakes; and it consists in theconstruction and novel arrangement of devices, as hereinafter set forth,and particularly pointed out in the appended claim.

In the accompanying drawings, the letterA designates the rear sled of abob-sleigl1,in connection with which the invention is illustrated,although it may be applied to sleighs of all kinds.

B represents the raves, O the runners, and D the shoes thereof.

- On each rave, near its central portion, or at the center, is located astrong plate, E, which -is formed with a slot, F, for the upper portionof a reciprocating dog, G, which is of laterallyflattened form, andextends downward through a guide'or bearing, H, on the runner. Thesedogs are made of sufficient length to extend,

when pushed downward, below the bottoms of the shoes, and they areoperated by rack-andpinion movement, each dog being provided with a rackon the edge of its upper portion, as indicated at K. I

The pin ions or segment-pinions L are seated on a transverse shaft, N,which is arranged in bearings, so that the pinions will be in positionto engage the racks of the dogs. The shaft is squared to receive thesquare eyes at of the pinions. The shaft N is made in two sections,which are held together bystraps or sliding connections, as indicated ats, so that itcan be lengthened or shortened to correspond to the widthof the sled. This adjustable shaft also provides a means whereby thepurchase end of the shaft can be laterally extended in case of a wideload to receive the end of the operating-lever V, which is designed toextend forward within reach of the driver.

Havingdescribedthisinvention,whatIclaim, and desire to secure by LettersPatent, is-

A sled brake consisting of reciprocating dogs extending throughguide-bearings on the raves and runners, and having rack-edges to engagepinions seated on a transverse squared shaft made in sections, andthereby adapted to be lengthened or shortened, substantially asspecified.

In testimony whereof I affix my signaturein presence of two witnesses.
